This description makes it sound like the...

This one is all wall outlet, no car. You obviously know what that's supposed to look like. For about the same price or less, you can go into just about any convenience, big box or hardware store and get a USB charger that will plug into both the car and the wall. They're usually sold for charging phones. Or, for another $10-20, you can go to an auto parts or electronics store and get a bigger AC/DC "inverter" that will allow you to use the cigarette lighter/accessory plug to charge and power USB and almost any 2-3 prong device. We use them for laptops, phones, headlamps, cameras...a blender...you name it and you can get juice to it.

This is a picture of the first charger I'm talking about. The kit we got will charge just about any kind of USB device we've ever tried, including almost any kind of phone, Kindles, i-pods, cameras...It's made by Cellular Innovations and cost about $20 at Walmart. Hope it helps.
